Copyright on sounds from old Flash sound library

Hi,

This is a question about copyright on sounds from an old Flash sound library.

In some ways this is probably more a question for Macromedia than Adobe, but I can't ask them, and I imagine that Adobe has inherited Macromedia's intellectual property, so...

There is a sound in an old Flash sound library called soundLib.fla, which I have a copy of. It is probably from Flash MX or earlier. I probably obtained it from the university I was teaching at, though I can't remember if I owned a copy of Flash back then or just used the university's resources. I kept it as a teaching resource because subsequent versions of Flash didn't include the sound library.

My query: I am curious as to the copyright status of the sounds in that library. There is one, Bucket Hit, that I would like to use in an animated artwork and am not sure if the sounds would be public domain or have a freely usable licence, or be more restricted, and want to at least try to find out before I decide whether to use it in the finished animation or not.

I've searched the internet for similar sounds that I can use (both freeware and paid) but haven't yet found one that is quite what I want.

Regards,

John
